The gear ll is rurried hythe inclined steering she it 15 having lhe hand Wheel 16 at, :the endopposite Lhe gear 1- and located adjacent to the seat 17. The seal 17 isconreuieully iuounled upon a platform 18 pr0- ien-ling from one side ofthe machine near its front portion, thus conveniently locating th soperator to oversee the operation of the machine in the performance ofits functions.

Situated area-r the front end of (he ma chine also. is a casing 19,preferably of cylindrical form in which is mounted a sucl.ion fun 20,the shaft 31 of which is operati-vel-y connected with the drive shaft ofihe inohor' 2 by means of -& sprocket chain or similar drivingconnection. In its low. the casing 19 is provided with a door :33 vwhich ready access may he had to ihe interior o-f the casing wherein thefan A receiving spout 24 :prog ects .elownwardly from the casing 19, theupper end of ihe spout being in communication vi-'ilih an opening in thehottomof the casing while the lower end of the spout is comp ed oflunged sections 24 adapted to fold iipi'iu d against the body of thespout when the. uiuchiuo is traveling over :1 field .uud ihe suctionmechanism is not being operai-locl. Books 25 or similar fnstenings mayhe oiuployei'l to hold the seeliol1s 2-'l oi ihe spout 24 elevuted toclear any 0b stllt'lls over which lho machine muv pass, and hook .35 areused to opemtively .conuool the sections.v

ii-culling oil vfrom the casing and approxiriimlely ol. a tangentthereto is a pipe or coni'luil 2%) which projects reurwnrdly of thefriuue of the nmehiue and terminates in a discharge spout 26, the wallsof which are imertiirecl. Suitable valves 27 in the form of sliding:plates are mounted on the Walls of the discharge spout 26, which opensdownwardly above the conveyor 28. and said valves have handles 29 forready msnipuhltiou of the same to close and open the apertures of thespout 21'5". By reason of the provision of the valves 1-7, the apertureswhereby to control the velocity of the airpassing through thedischargeopening in the bottom of the spout, for a purpose to be more fullypresented hereinafter.

By reason of the arrangement of tll'd receiving spout 2440f the casing19, it will be,

apparent that while the machine is propelled over the field, the fan 20may be driven at high speed to ,create-sufiicient suction at the spout24 to draw into the casing, the hay to be harvested. As the hay is drawnthrough the spout 24into the casing '19,-it is driven or forciblyejected from the casing 19 by the fan 20 into the conduit or pipe26 andthe blast of air created by the fan 20 is suliicient to force thematerial swiftly to the discharge-end of the conduit.

From the discharge spout 26 of the con-,

' for-operating the conveyer belt. The free end of the frame 29 issuspended from a counterbalance beam 32 by the bail 33, said beam beingprovided with an adjustable weight 34, whereby upon a certain f'OllIltof hay being deposited upon'the bin, the frame L29 will. be moveddownwardly to bring the wheels 30in contact with the 4 ground. Upon thewheels contacting with the ground, the conveyer belt is immediately putinto operation for depositing its shock of hay or other material on theground, and after the belt is relieved of its lead, the frame 29 assumesits normal raised position due to the influence of the weight 34;

The function of the fan 20 is to a;certain' extent dual in that saidfan'not only draws or sucks the hay into the casing 19 but by mechanicalcontact \vithth'e material aforesaid, acts thereon to eject it into theconduit 26. y a

It is contenip'laled 'that certain of the minor features of constructionof the invention may be modified in accordance with the Witnesses:

vanced over the ground, acasing carried by said support, a suction fanmountedin said casing, and a receiving spout at the lower portion of thecasing and terminating proximate to the groundjwhen in an operativeposition, said spout comprising hinged sections, each of which isindependently movable into an uprai'sed inoperative pos tion to clearobstacles upon the ground.

2. Ina machine of the class described, the

combination of a support adapted to be advanced over the ground, acasing carried by said support, a suction fan mounted in said casing, areceiving spout at the lower portion of the casingand terminatingproximate to the ground whenin operative position, said spout comprisinghinged sections,

each of which is independently movablejnto an upraised inoperativeposition toclearobstaclesupon the ground, means for securihg thesections together when the'spout is in the operative position aforesaid,and other means for holding each of said sections in the upraisedposition.

3. In a machine of the class described,the combination of a supportadapted to be advanced over the ground,-a casing arranged thereon, asuction fan in said casing, a discharge conduit connected with thecasing and having a discharge spout provided with a discharge opening,said discharge spout being also provided with apertures adjacent to saiddischarge opening, and valve means controlling the operative area ofsaid apertures, said means comprising, .apertured plates s'lidablymounted with respect to the spout, the apertures in said plates beingregistrable with the apertures in the spout,

whereby movement of the plates will regulate the size of the openingsthrough the spout.

In testimony whereof I-alfix my signature in presence of two witnesses.
